Replica wormhole as a vacuum-to-vacuum transition

Abstract The recent developments related to the black hole information paradox have brought us a confusing object: replica wormhole. We are trying better understand object from viewpoint of thermo-mixed double and spontaneous symmetry breaking. In this paper, we show that wormhole can be regarded as transition between different degenerate vacua, corresponding gravitational partition function should controlled by manifold vacua. also check in two-dimensional Jackiw–Teitelboim gravity saddle is indeed dimension Moreover, it suggested geometries connecting vacua measurement process soft hair compares vacuum configurations.
